When Gaming Is Good for You

University of Rochester researchers found that people who play videogames have better hand-eye coordination, make faster decisions and are possibly more creative. Gee guys, those results have been coming out for years. In fact, there’s a whole books dedicated to the subject. Wall Street Journal reporter Robert Lee Hotz pares down the medical terms and puts the findings in common English.

Videogames can change a person’s brain and, as researchers are finding, often that change is for the better.

A growing body of university research suggests that gaming improves creativity, decision-making and perception. The specific benefits are wide ranging, from improved hand-eye coordination in surgeons to vision changes that boost night driving ability.

People who played action-based video and computer games made decisions 25% faster than others without sacrificing accuracy, according to a study. Indeed, the most adept gamers can make choices and act on them up to six times a second—four times faster than most people, other researchers found. Moreover, practiced game players can pay attention to more than six things at once without getting confused, compared with the four that someone can normally keep in mind, said University of Rochester researchers. The studies were conducted independently of the companies that sell video and computer games.

Scientists also found that women—who make up about 42% of computer and videogame players—were better able to mentally manipulate 3D objects, a skill at which men are generally more adept. Most studies looked at adults rather than children.

Electronic gameplay has its downside. Brain scans show that violent videogames can alter brain function in healthy young men after just a week of play, depressing activity among regions associated with emotional control, researchers at Indiana University recently reported. Other studies have found an association between compulsive gaming and being overweight, introverted and prone to depression. The studies didn’t compare the benefits of gaming with such downsides.
